3G unable to find wifi networks
my 3G is unable to find wifi networks. Recently "updated" to 4.0.1 then 4.0.2. Immediately began having occasional loss of connection or need to re-enter wifi password. Now unable to find any wifi networks (known to be up/working) for more than a week.
Tried restoring as new and from backup, reset network settings, deselect spotlight search, reset, etc. multiple times.
I do have a wifi address listed on the phone.
Phone is pairable via bluetooth and GPS works.
I know there has been no recent trauma to the phone.
Does this sound like hardware, or software bug?
Is this a good question?
